摘要
环境绿化目前在公路建设中越来越受到重视,它不仅能够美化环境,而且具有防护、生态保护的能力。为了充分分析、评价已建公路的工程绿化状况,对公路绿化工程进行分析评价,是非常必要和紧迫的。目前,高速、一级公路的绿化已得到普遍重视,而作为二级公路的绿化却研究得甚少。为此,本文通过对绿化功能分析,提出了二级公路绿化评价指标体系框架,该体系评价指标包括:边坡防护能力、路侧生态防护性以及景观效果;并结合我国江苏公路绿化的具体情况,提出了基于回归分析和层次分析法的二级公路绿化的评价方法,该方法运用在实践中能够客观地评价二级公路的绿化效果。
Highway green landscape is an important part of the highway systems to provide landscape scenic view and other functions such as soil stability enhancement capability in slope embankment area,and environmental ecologic protection capability in roadside area.In order to have highway green landscape perform good quality,adequate maintenance should be routinely performed.Thus,field survey activities should be carried out to evaluate the quality of highway green landscape.Now freeway and first grade highway green landscape have been concerned,but second grade highway green landscape has not been researched.Through analyzing the function of greening,this paper summarizes a research project that was to develop evaluation procedures and models for green landscape evaluation.The main evaluation indices considered in the evaluation procedures and models are soil stability enhancement capability in slope embankment area,and environmental ecologic protection capability in roadside area.In addition,landscape scenic view quality is another important factor that affects green landscape quality.The main purpose of the models is to convert evaluation indices to an overall quality measure,representing the overall quality of the second grade highway green landscape.The conversion is based on linear regression models and AHP method,basing on highway in Jiangsu.These models can be used to more objectively evaluate highway green landscape.
